What does it mean when the JS WebSocket network connection is disconnected or lost?

edit

When the JS WebSocket network connection is disconnected or lost, it means that the communication channel between the client and server has been interrupted or closed. This can happen due to several reasons such as network connectivity issues, server downtime, client-side or server-side errors, or manual intervention. When the WebSocket connection is lost, the browser cannot send or receive data from the server, and the application may stop working properly until the connection is re-established. It is important for developers to handle WebSocket disconnections gracefully and implement appropriate reconnecting mechanisms to ensure uninterrupted communication.
